have a look at e2save.com aswell. they do similar things, and also good cashback deals. im on my 3rd deal thru them. got a "clearence" samsung u600 (ie one that has been sent out and returned for some reason, but is brand new and still under warantee/guarantee whatever) on a 12 month contract with 12 months free via cashback on o2s £40 tarif (500 mins/600 texts per month). They are safe as aswell cos they're part of the carphone warehouse. have a look at their site, and it might be worth ringing them too, as thats how i got my latest deal.
